Example value with engine on: 0.90 -
1.10mV
In closed loop, the value must be close to 1.00
(values not within the 0.90 - 1.10 interval indicate
a fault): for example, value 0.75 corresponds to
+25% with respect to the reference injection time;
1.25 corresponds to -25%. In an open circuit, the
lambda probe signal is too low. Therefore, the con-
trol unit takes it as a lean combustion condition and
will try to enrich it. The value read will be 0.75: once
this correction has been tried, the value shifts to
1.00 fixed and the Lambda probe error is signalled
CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING,
CAREFULLY READ THE GENERAL TROUBLESHOOTING
CONCEPTS FOR ELECTRICAL DEVICES AT THE BEGIN-
NING OF THE CHECK AND CONTROL SECTION IN THE
ELECTRICAL SYSTEM CHAPTER.
DIAGNOSIS INSTRUMENT: STATUSES
Lambda probe: Start-up_Lean_Rich_Fault due to rich value_Fault due to lean value
•
If the probe connector is removed (voltage almost equal to zero), the status is Fault due to
lean value
Lambda check: Open loop/Closed loop/Rich in closed loop/Lean in closed loop/enriched
•
Closed loop indicates that the control unit is using the lambda probe signal to keep the
combustion as close as possible to the stoichiometric value.
DIAGNOSIS INSTRUMENT: ACTIVATION
Lambda probe heating
•
The injection relay (No. 33 in the wiring diagram, placed under the saddle next to the battery,
right side; CHECK, however, the identification of the relay with the colour of the cables) is
energised and the heating circuit is closed to ground 5 times (pin 3 of the lambda probe
connector). The continuity of the wiring is necessary for correct activation: no error indica-
tions are displayed in case of lack of activation
DIAGNOSIS INSTRUMENT: ELECTRICAL ERRORS
lambda probe P0130

shorted to positive
Error cause
•
Excessive voltage (battery voltage) has been detected at PIN 10 and 22 of the ENGINE
connector. Caution: the 'lambda probe' parameter is not the real value that is read; a re-
